Patented Sept. 28, 1943 I UNIT D LSTATE MEANS FOR LOOKING VEHICLES AGAINST Y 1 SELF-PROPULSION. v Maxiinilian E. Zimniermanii, L os An geles Calif.

lApplieationJfindlG, 1'941, Seria1No. 398,282 "10 Claims. (01. va -19a) This invention pertains to a device for locking vehicles against self-propulsion. r

Inmany States ordinances have been enacted which prohibit locking ing moved by force. externally applied thereto. By thi invention the vehicle is not locked in such a manner as to disregard suchorclinances, but is, nevertheless, locked in suchaway that u'nauthorized persons cannot utilize its own propulsive power to drive it away.

Among the objects of the invention are:

To provide an improved manually operable key controlled locking means movable ,to and from a position wherein it obstructs either the clutch pedal or brake pedal or, if desired, both of said pedals; to provide a device of this character apan automobile against 'be-' plicable to a number of difierent make of. auto- I mobiles and without altering their construction; and, to provide a I kind which can be installed conveniently and without unnecessary expense upon many difierent types of cars now on the market.

There'have been heretofore constructed lock-.

ing devices for automobiles wherein. pedal obstructing means are carried by a slidable bar extending along the steering post column at the side thereof which i nearest to the operator, thus obstructing more or less the space tween the steering column and the front seat of the vehicle. By this invention this objectionable featureis avoided because the'means for operat ing the pedal obstructin arms is located at that side of the steering column which is farthest from the operator. 7 v K The invention includes the combination of the locking means set forth with those manually op-;

locking device of the foregoing which is beerable partsof the car which it controls, and'also includes anew article of manufacture capable of being separately made and sold for subsequent installing upon the vehicles which it is desired to equip therewith. e

In itsbroader aspect the invention includes lock-controlled means for at will rendering inoperative either manually operable or foot-operable means necessaryfor the driver to use in driving his car, and isnot limited to use in the specific situation in which it is illustrated in the drawings. I

Referring which illustrate desirable embqdiments'of the in venti'on,

Fig. l is a side elevation of the device, showing the same applied to an automobile parts of which are indicated by broken lines. Except asto concealed parts the device is to the accompanying drawings,

shown in it 1ocked'po-' sition in full lines and in its'unlocked position in brokenlines. 'A part of the device is broken away to showunderlying structuremore clearly. 1

Fig. 8 is a section the plane of which is indicated by the line 8-8 on Fig. '7.

Figs. 9 to 13 showmodifications of the structures-of Figsl to 8, one of these modifications pertaining to forming the pedal arresters in a single piece. 4 h

Fig. -9 is a side elevation looking from left to right (fromv the viewpoint of the driver), a part of the structurebeing broken awa in the left portion of the View, and. some conventional parts being shown by broken lines.

' Fig. 10 illustrates the device as viewed from in front, a part being broken away to show underlying structure. a

Fig.11 is a crosssection on line He! l of Fig. 9, the scale of which is larger than in the latter view.

of mg 9 7 Fig. 13 is a reproduction of Fig. 12' except that one of the parts is shown in two pieces instead of in the unitary form shown in Fig. 12. I

Referring in detail to. Figs. 1 to 8"of the'drawings, the device is shown installed upon an auto-' mobile havinga conventional steering wheel it that surmounts basal attachment a stabilizing bracket [3 through whichit'passes,

said bracket being carried by the cowl (not shown) In'order to attach thedevice to which thein-i vention pertains to the steering column ll, a 1

bracket I5 is clamped to said column, said bracket including the arcuate hinged together'at l8 Fig. 12 is a sectional detail taken on line l2-I 2- a steering column ll having a' 12 and at about its midheight' clamping jaw l6 and I1 and respectively furnished" 7 guide and support within which is slidably fitted a bar 32 having at its upper end the locking head 38 and carrying at its lower end radially extending locking arms 33 and 33a whereby the pedals 34 and 35 are at will locked against depression. With said locking head 38 cooperates a locking means 39 carried by the upper part of the aforesaid extension 3| and consisting of lock-bolt 45 held engaged by spring 4'! and retracted against the opposition of said spring by a key 4! as indicated in Fig. 4. The locking of pedals 34 and 35 is thus quickly and easily efiected by slightly raising the arresters 33 and 33a into locking position by the finger-hold 31, and releasing of the pedals, 1

is efiected simply by a slight turn of the key M. This portion of the device is constructed alon conventional lines, modified for the particular purpose and to fit into the general scheme and outline of the device- Care is taken to prevent tampering with the device by eliminating screwed orbolted joints or parts through welded or cast construction.

The aforesaid slidable bar 32 is furnished near its upper end with a forwardly projecting'exten sion 31, shown as an arcuate lug or shortarm having its concave side directed downwardly, thus aiiording a convenient finger-hold for manually sliding the bar upwardly to bring a locking tooth or shoulder 38a carried by its upper extremity into a locked engagement with aforesaid locking means 39.

In Figs. 1, 2, 7 and 8 the locking arms 33;: and 33 are shown contoured, by reason of interlocking projections 44, to interengage each in an adjustable, nonswinging relation to each other. "Integral with the lower end of the slidable rod 32 is a screwthreaded extension 42 which is reduced in diameter thus providing an annular shoulder 43 thereabove against which abuts the apertured end portion of the upper arm 33a. The lower arm 33, however, has at its inner end a screwthreaded aperture 33b for screwing onto the screwthreaded part 42. The lower arm is threaded, as stated, and the upper arm is free from threads, so that the arms may be adjusted to different angular relations to each other and then attached as shown in Figs. 1 and 2. After these arms have been adjusted and attached, the lower end of part 42 may be peened over as shown at 46 to prevent tampering with the arms.

In Fig. 3 the locking portion of the device and the clamp are shown. The locking portion is illustrated in Fig. 4' and the clamp in Fig. 5.

The modifications shown in Figs. 9 to 13 difier only in a few details from the former the invention already described, one of which is in regard to an arcuate shield plate 5! which is in; a fixed relation to the slidable bar 32, either by the means shown in Fig. 12 or by the construction shown in Fig. 13, and prevents the clamping bolts 59 from being tampered with when said bar 32 is in its upper, pedal looking position. In Fig. 12 said shield is shown made integral with a one piece approximately U-shaped pedal locking member v united by a hinge 51.

Lil

33x having through its central basal projection 52 a vertical bore to receive a diametrically reduced unthreaded part 54 of the slidable rod 32. This structure isassembled and made secure by means of a riveted pin 55, the end of which may be peened over.

The structure shown in Fig. 13 difiers from that of Fig. 12 only in that the shield like is made in a separate piece and has a diametrically reduced tubular foot or hub portion 5| y fitted within a bore which corresponds to the bore occupied by part 54 in Fig. 12, the securing pin passing through this hub portion.

InFigs. 9 and 11 two columns are provided for, the steering column H and the smaller, gear shifting column Ha: found on some cars; and a modified clamp is used which includes jaws 58 In using this modified clamp the two screw type bolts 59 are used without nuts, and these bolt are protected by the side of the shield5l when the device isadjusted to the pedal locking position. Adjacent to the hinge 51 each jaw'58 is arcuated to fit the steering post and is of a resilient, relatively thin character to augment the' grip upon the post II when the clamping bolts are screwed down, but at 58a and 58b the jaws are furnished with internal shoulders to lengthen, their clamping surfaces.

In all the forms of the invention which have been described, whenever the locking bar 32 is released by turning the key 4|, said bar automatcally gravitates to its lowermost position wherein theparts of the device which underlie the pedals occupy so little" vertical space and lie so closeto the floor of the vehicle that they do not interfere with the pedals being depressed as far as is ever required for the proper operation of the vehicle.
